The stone buildings and monuments of Kiel (Germany) is a World Heritage Site. Granite, sandstone and limestone are used in architectural structures. As a result of the study of cyanobacteria in biofilms on the surface of stone structures and monuments in the city of Kiel, 28 species taxa, 18 genera were identified. Phormidesmis sp. is the most common species. The largest number of species has been recorded on limestone (17). Further study of cyanobacteria using molecular methods is planned.
